Purpose
This notebook summarizes eBird sampling (effort) within North Carolina for the past 5 years. Sampling data can be downloaded from the eBird website and queried with eBird’s R package named “auk”. The script named “filter_eBird_sampling.R”, which is saved in the NCBA github repo, performs the filtering that supports this notebook.
The records available from the sampling data set are for individual, unique checklists and several attributes are included for each. This notebook summarizes the available attribute values to learn as much as possible about the modern eBird effort to date within North Carolina. The available checklist attributes are:
checklist_id, last_edited_date, county, county_code, iba_code, bcr_code, usfws_code, atlas_block, locality, locality_id, locality_type, latitude, longitude, observation_date, time_observations_started, observer_id, sampling_event_identifier, protocol_type, protocol_code, project_code, duration_minutes, effort_distance_km, effort_area_ha, number_observers, all_species_reported, group_identifier, trip_comments

Checklists per Atlas Block
Although coordinates are provided by eBird for checklists, they do not provide precise locations of eBirder effort for two reasons. First, there are limits to the spatial precision of the points due to gps precision and/or observers ability to identify exactly where they birded on a map or in the app. Second, many birders travel while birding but their paths are not available, only the distances they traveled.
Locational uncertainty is important because if it is large in relation to the level of analysis, it creates uncertainty about which spatial subregions, such as counties or atlas blocks, a checklist should be attributed to. One approach is to assign each checklist to the subregion that the checklist coordinate is located within. That approach could generate deceptive results if checklists represent birding effort from multiple blocks but are assigned to a single block or if the coordinate is located in a block adjacent to where the birding actually occurred. I present results from this approach below for reference and coarse data summary and refer to it as “coordinate count”.
Another approach is to use checklist polygons instead of the coordinates (points) in order to include the locational uncertainty in the summary. Under this approach, coordinates are buffered with the distance traveled by the observer during the checklist period. Each checklist is then assigned to all of the blocks that the polygon intersects in order to acknowledge that the checklist could represent effort from multiple blocks. Results from this approach can logically be expected to exaggerate the true footprint of birding effort and suggest blocks were sampled that actually were not. The results are forthcoming.

Observers
All observers
Most eBirders have only submitted a handful of checklists. The median number of checklists submitted is only 2, and observers who have submitted more than 6 are in the top quartile for number of submissions.
Core observers
It is informative to look more closely at a subset of active observers in order to better characterize observers who may participate in the atlas. Here, I exclude the extreme outliers and people with fewer than some arbitrarily “small” number of submissions (20).

- The durations of most checklists are less than one day (1,440 minutes), but 25 checklists carried on longer than a day and 552 checklists lasted between 12 and 24 hours.
- I omitted checklists longer than 12 hours for the summaries in this section.
